Hi I have an 02 4.6 have a problem with the fuel gauge. When it went down to quarter kept going till through the red it now won't register when any fuel goes in petrol light stays on and fuel gauge does not lift and won't register on computer any miles left I have filled the tank no difference. The first time it happened I lifted back seat and took plug of passenger side sensor and put it back on it worked but now nothing has anyone any ideas or had this problem I can get a sensor of eBay but don't know if this is the problem.
